{"id":"CVE-2025-47771","aliases":["GHSA-f5cx-h789-j959"],"url":"https://o3.security/vulnerability/CVE-2025-47771","summary":"PowSyBl Core allows deserialization of untrusted SparseMatrix data","details":"PowSyBl (Power System Blocks) is a framework to build power system oriented software. In versions 6.3.0 to 6.7.1, there is a deserialization issue in the read method of the SparseMatrix class that can lead to a wide range of privilege escalations depending on the circumstances. This method takes in an InputStream and returns a SparseMatrix object. This issue has been patched in com.powsybl:powsybl-math: 6.7.2. A workaround for this issue involves not using SparseMatrix deserialization (SparseMatrix.read(...) methods).","published":"2025-06-19T23:41:41.357Z","modified":"2026-08-12T15:13:31.549527Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"com.powsybl:powsybl-math","fixedVersion":"6.7.2"}],"fix":{"url":"https://github.com/powsybl/powsybl-core/commit/8ed16ce41683c4aef5f6aa1dd5ae8642aa5ed2bd","label":"powsybl/powsybl-core@8ed16ce"},"references":[{"type":"WEB","url":"https://github.com/powsybl/powsybl-core/releases/tag/v6.7.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/47xxx/CVE-2025-47771.json"},{"type":"ADVISORY","url":"https://github.com/powsybl/powsybl-core/security/advisories/GHSA-f5cx-h789-j959"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-47771"},{"type":"FIX","url":"https://github.com/powsybl/powsybl-core/commit/8ed16ce41683c4aef5f6aa1dd5ae8642aa5ed2bd"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T15:13:31.549527Z"}}
